Unspeakable Things: Sex, Lies and Revolution is a 2014 book by British journalist, author and political activist Laurie Penny.

Penny also writes about her own struggles with an eating disorder, her career in journalism and experiences in activism and the British underground.

In addition, the book discusses misogyny and political organisation on the internet, protest, poverty, feminist hostility towards sex workers, sexual freedom and the failure of the Occupy movement.

In The Guardian, journalist Gaby Hinsliff praised the writing style and noted "for all her contradictions and irritatingly sweeping generalisations, when she's right she is very right" and "you find yourself nodding too many times to ignore it: when she explores the media's obsession with 'fucked up white girls, beautiful broken dollies, unable to cope with the freedom and the opportunities they've inherited'.

Wyatt criticised the book for being "provocative" and "dramatic" and condemned Penny for including too much personal information, such as writing about being caught masturbating, losing her virginity, and a section in the book in which Penny notes "she has slept with numerous nerdy male activists, and some women – sometimes with both at the same time".
